BARREL-HOOPING MACHINE.

SPECIFICATION forming part of Letters Patent No. 454,803, dated J' une23, 1.891.

Application filed September 23, 1890. Serial No. 365,918. (No model.)

T a/ZZ whom it may concern.-

Be it known that I, LEONARD D. MORRISON, of New York, in the county ofNew York and State of New York, have invented a new and usefulImprovement in Barrel-Hooping Machinery, of which the following is afull, clear, and exact description, reference being had to theaccompanying drawings, forming part of this specification, in which-Figure lis an elevation of a barrel-hooping machine provided with myimprovement. Fig. 2 is a side view partially broken away and showing thedrive-arms provided with hand-pieces adapted to engage with thechinehoop. Fig. 3 is a similar view, the chinehoop being driven home.Fig. 4 is a like view of the upper part of a barrel, showing thehand-pieces in position to drive the catchhoop. Fig. 5 is a bottom planview of one of the hand-pieces. Fig. 6 is a cross-section on the line VIVI of Fig. 5, and Fig. 7 is an elevation of the same.

Like symbols lof reference indicate like parts in each of the figures.

My improvement consists in a combination of devices for putting the endor chine hoop on wooden barrels, and it is designed to be used inconnection with the well-knownvbarrel-hooping machines 1n which a numberof Vertical arms are pivoted to a frame or head,

which is threaded so as to form the nut of the screw by which the armsare raised to enable the arms to engage the hoop which is to be drivenand lowered to drive down the hoop over the staves of the barrel. Asordinarily constructed in trussing-machines, these arms are arranged atequal distances around the barrel and are hooked or notched at theirupper end, so as to enable them to engage the hoop and thus draw it downas the arms are simultaneously lowered by the screw which operates thehead to which they are attached. As the chine-hoop is of iron andpresents its thin edge to these hooks or notches, of the ordinaryconstruction, just mentioned, the hooks have a Very narrow bearing uponthe hoop, and the result is that the hoop Ais apt to be strained ortwisted, in which case it will not lie .evenly on the surface of thestaves, especially if, as is aptto be the case, it is bent at the pointwhere the arms engage it. To

enable the arms to take a wider and more .uniform hold on the .upperedge of the chinehoop, I have made my improvement, which consists in theuse, in connection with the vertical arms of the machine, of hand-pieceshaving guide-ribs, substantially as hereinafter described, one of whichhand-pieces is preferably detachably connected with the upper end ofeach arm, which hand-pieces, 6o extending outwardly on each side of thedriving-arms and being curved in the shape of the arc of a circle andhaving a groove, substantially corresponding in curvature to thechine-hoop, into which the chine-hoop enters, draw down the hoop withuniformity, and thus prevent its being twisted or bent, as beforedescribed.

My improvement is especially designed to overcome the difficultyexperienced in barrel- 7o hooping machines of ordinary construction,that the chine-hoop, when first placed onthe barrel, is unsupported byit, excepting slightly at its lower edge, and that it is very difficultby means of machinery acting on the hoop to 75 draw or force it downwardonto the barrel without either pushing it inward or pulling it outward,thus bending the hoop out of shape and rendering it unfit for use.

Referring to Fig. 1 of the' drawings, a rep- 8o resents the verticalscrew-shaft by which the machinery is operated, having a horizontalbevel-wheel b keyed thereto, which wheel meshes with a bevelpinion c,keyed to a power-shaft c', which is driven by power ap- 85 plied in anyconvenient manuel'. On the shaft c is a cross-head, the hub d of whichforms a screw-nut within which the screwshaft a turns. From the hub dspokes e branchradially, of any desired number, of uni- 9o formlength,tothe extremities of eachof which is pivoted one of the arms f, whichextend upwardly in a substantially vertical direction around or throughapertures in the base-plate or table m, on which the barrel to be hoopedis placed, so that as the vertical shaft d is revolved in one *directionor the other the crosshead and the arms pivoted thereto arecorrespondingly elevated or depressed, the arms being slightly curved soas to accommodate roo them to the bilge of the barrel and to cause theupper end to approach the chine of the hoop g.

barrel sufficiently close to engage the chine- The arms f are held inposition by the adjustable springs which are secured to the arms by aloop and wedge h, or otherwise, as may be found convenient, and bearagainst the outer extremity of the spokes e of the cross-head. Thesearms fare not hooked at the upper end, as in the ordinary constructionsbefore described, but are or may be of substantially uniform width andthickness with that portion of the arm which when the arms are elevatedsurround the barrel. A slotted hand-piece h (shown in detail in Figs. 5,G, and 7) is secured to each of the arms f, near to its upper end, bymeans of a key 71.2, or by a set-screw, or otherwise, as may bepreferred. Each of these hand-pieces may be curved and project on eachside of the arm to which it is attached, the projections bein gpreferably of equal length on' each side of the arm, so as. to give afirm hold and uniform bearing on the outer edge of the chinehoop. Thecurved proj ectiontl is also hanged inwardly toward the center of thebarrel, so as to form a ledge j to rest on the top of the catchhoop, anda groove 7c in the under side of theledge,havingsubstantiallythesamecurvature as the chine of the barrel,serves to receive the upper edge of the chine-hoop and to prevent itsbeing bent out of shape when being driven home. This groove should besubstantially V-shaped in. cross-section, so as to receive the hoopreadily and yet hold it firmly to its circular form without permittingit to be bent, crushed, or twisted out of shape, the bottom of thegroove, however, not being pointed at its inner end but wide enough toreceive and hold the hoop without permitting it to get wedged orfastened in the groove. On the under side of the hand-pieces are ribswhich extend to the outer edge of the groove 7c, as shown in Figs. 5, G,and 7, the

l function of which will be described hereinafter.

The operation of the machine will vbe readily understood from what hasalready been stated, the arms f being actuated in the usual manner bythe cross head d e and screwshaft a.

In Figs. l to 4c I have shown a catch-hoop n, the purpose of which is todraw the staves closely together at the chine of the barrel, so as toenable the chine-hoop to be more readily placed in position to be drivenhome by the hand-pieces h on the arms f. This catch-hoop consists of ahoop, (see Figs. 2 and 3,) preferably of iron, slightly larger incircumference than the chine of the barrel, having a radially-projectingarm 0^, which is pivoted to a plunger p, placed within the tubularcavity ofa hollow standard q, and resting on a spiral spring s,contained therein. The standard q may be secured to the table m. At theouter end of the arm fr', beyond its pivotal'point, is an adjustablebalance-weight r. `The catch-hoop n is readily placed over the chine ofthe barrel or raised therefrom by means of the weighted and pivoted armfr, the spring-piston p permitting the arm to be raised from a pivotalpoint. This will be sufficiently obvious from inspection of Fig. 2 ofthe drawings,where the catch-hoop is shown by dotted lines in anelevated position.

It is not necessary for me to describe the details of construction ofthe catch-hoop more fully, as it is the-invention of another. The barrelcomposed of staves held together by truss-hoops is placed on the table mof the machine, and then the catch-hoop 'n is lowered over the chine ofthe barrel and is drawn down by the hand-pieces h to the position shownin Fig. l. The chine-hoop g is then placed on the chine of the barrel,as shown in Fig. 2, the arms f are again elevated and lowered, so thatthe hand-pieces 7L engaging the hoop drive it into place, forcing thechinehoop downward uniformly, so as more forcibly to draw the stavestogether, and thus hold the barrel-head very firmly in place. Thecatch-hoop is then lifted off the barrel,which is 11p-ended, and achine-hoop is driven on` the other end of the barrel in a like manner bymy apparatus.

As a general rule the staves ofthe barrel when it is put together arestill warm, and when they cool after the barrel is formed a certainamount of shrinkage takes place. The chine-hoops, therefore, are notdriven completely home when the barrel is irst formed, and sometimes,therefore, project slightly above the chine of the barrel and are liableto be bent or driven home by resting on the flat surface of the table mwhen the chine-hoop at the other or upper end of the barrel is beingoperated on by the drivingarms. To obviate this difficulty I employ apreferably circular plate w, (shown in Fig. 3,) which is slightly lessin diameter than the chine-hoop, and is secured to the face of the tablem, so as to support the barrel by the staves, and prevents thechine-hoop from-f'being driven home or bent by the downward pressure ofthe driving-arms on the chinehoop at the upper end of the barrel, thechine of the barrel resting on the beveled edges of the circumference 0fthe plate.

' In lieu of a circular plate,a polygonal plate might be used, or anumber of arms projecting radially, like the spokes of a wheel. Thisplate w is not claimed in this patent, as it may be used in conjunctionwith another similar plate for partially driving the chinehoop and formsthe subj ect-matter of another application for patent filed June 3,1891.

On the inside of the hand-pieces 7L area number of vertical projectionsor ribs ,which extend on the ledge il of the hand-pieces t0 the outeredge of the groove ltr/,where they terminate, as shown in Figs. 5 and 6.The purpose of these ribs is to prevent the handpieces from coming closeenough to the barrel to permit the ledge t' to engage the chine whilethe catch-hoop n is on the barrel and` IIO ribs on their inner face,each hand piece having a curvature substantially that of the chine ofthe barrel, and a similarly-curved and substantially V-shaped groove inits under surface to engage the upper edge of the chine-hoop,substantially as and for the purposes described.

In testimony whereof I have hereunto set my hand this 2d day of August,A. D. 1890.
